- Confirm the association of the X-ray source with the Sey 2 galaxy
- unabsorbed power law spectrum Gamma=2.3
- 2-10 keV flux of 2.4e-13 erg/cm2/s

Malizia et al. 2009 (MNRAS):
- Broad band (XMM+INTEGRAL) spectrum is flat + prominent iron emission line =>
indicative of a Compton thick Sey 2.
- Spectral fitting of the spectrum <=> 3 models can represent
the data well:
- one representing transmission where some of the high
energy radiation penetrates trough the thick absorption and is observed
with the reflection from the surface of the thick torus
- one of pure reflection, where the primary continuum is completely supressed
- one of complex absorption involving partial covering by different absorbers.
- Absorption > 1.5e24 cm-2 in all 3 cases =>Compton thick
- Based on recent observational and theoretical findings favour the complex absorber (but
no scenario can be fully confirmed from the data).
